Unmanned ground-based hygiene maintenance vehicle and method for improving hygiene conditions

An unmanned ground-based hygiene maintenance vehicle, UGV, comprising:

• a housing having a base plate, a top plate and at least one housing side wall that is substantially perpendicular to the base plate;
• at least one wheel drive, which is in the housing;
• at least one wheel, which is coupled to the at least one wheel drive and in a recess in the base plate;
• a plurality of sensors for sensing an environment of the UGV;
• a controller for autonomous location and navigation of the UGV on a basis of sensing parameters of the plurality of sensors;
• an articulated robot arm mounted on or through the top plate of the housing and configured to support a hygiene maintenance tool;
• a hygiene maintenance tool supply module connected to the hygiene maintenance tool;
• at least one load-receiving element that is coupled to the at least one housing side wall and extends outwards from the at least one housing side wall, the at least one load-receiving element comprising a load support surface for supporting the hygiene maintenance tool supply module with respect to a vertical direction which extends transverse to the base plate;
• and
• a tool carrier mounted in the at least one housing side wall and a tool coupled to the tool carrier, the tool being arranged to support the hygiene maintenance tool supply module in position on the load support surface.
